Dear Reader,

It’s becoming increasingly clear the virus that causes Covid-19 can impact most organs in the body. The thyroid gland, however, wasn’t on the list — until now.

So far, there’s no evidence the virus that causes Covid-19 spreads through the water. This is in part because chlorine kills SARS-CoV-2 and also keeps viral particles from floating around the pool.
